"Severe thunderstorms are likely to produce damaging winds and heavy rainfall that may lead to flash flooding in the warning area over the next several hours," the alert said.

Areas that may be affected include Warwick, Gatton, Emerald, Gin Gin and Clermont.

Heavy falls have been recorded at Mt Fort William, south of Gladstone, where 52mm of rain fell between 1-2pm (AEST).

Queensland Fire and Emergency Services (QFES) is warning residents in affected areas to be prepared, while Premier Annastacia Palaszczuk has again urged Queenslanders not to attempt to drive through flooded areas.
